For PIM on IPv6, if the interface that was being used as the BSR candidate address
went down, the network occasionally did not re-elect a BSR and the RPs in a
timely manner. This could cause the router or switch to reboot.

If a user created a configuration file that contained port trunk settings before
VLAN port settings, then a loop occurred when the switch rebooted with this
configuration.
This issue has been resolved.
CR00013457
VLAN
1
When ports were added to a currently-disabled RSTP domain, the ports could
start to discard packets (because their STP state was set to Discarding).
This issue has been resolved. When ports are added to a disabled RSTP domain,
they remain in a Forwarding state.
CR00013492
OSPF
1
When route filters (made with the command add ip route filter) were used to
filter OSPF routes, it was possible for OSPF to constantly remove and re-create an
AS-External LSA. This could prevent OSPF sessions from establishing.
This issue has been resolved.

IPv6
2
The router or switch sometimes forwarded packets to directly connected hosts
whose corresponding IPv6 ND cache entry was still in INCOMPLETE state. This
caused it to send the packets to incorrect MAC addresses and egress ports.
This issue has been resolved.

If IGMP snooping was enabled but IGMP was not enabled, the snooper behaved
as if IGMP snooping fast leave had been enabled even when it had not been. This

the switch sometimes rebooted while processing topology change notifications
(TCNs).
This issue has been resolved.
CR00012741
Core, File,

2
The command create config=filename set did not copy the configuration file
to all switches in the stack, but only saved the file onto the current switch.
This issue has been resolved.
CR00013081
Switch, STP
2
When STP was enabled on ports in a trunk group, the non-master ports did not
have the same state as the master port in the switch’s hardware STG table. This
could, on rare occasions, create a broadcast storm.
This issue has been resolved. All ports in a trunk group follow the master port in
the hardware STG table.
CR00013128
ATM
2
When connected to some types of DSLAMs, the router could reboot due to a
reception error on the SHDSL EOC channel.

When the HTTP proxy URL filter had entries that allowed certain domains and
also had entries that denied certain keywords, the supposedly-allowed domains
were denied if they contained the denied keywords. The proxy allowed the page
/index.html from such domains, but no other pages.
This issue has been resolved. The proxy no longer checks allowed domains
against the keyword list.

IPv6
3
Previously, if IPv6 had a dynamic Neighbour Discovery cache entry for a particular
IPv6 address, it prevented users from adding a static entry for the same IPv6
address.
This issue has been resolved. Users can now overwrite dynamic Neighbour
Discovery cache entries with static entries.
CR00013117
IPv6, PIM,
PIMv6
3
A router or switch running PIM6 occasionally rebooted in certain network
topologies when links were very busy. The circumstances that caused this crash
are very unusual, but the code has been made more robust to cope with them.

ISAKMP
3
When heartbeats fail for an ISAKMP SA, the router or switch (correctly) removes
the ISAKMP SA and any IPsec SAs that were created by the ISAKMP SA. It then
sends delete messages to notify the peer, so that the peer can also remove the
relevant IPsec SAs.

However, if heartbeats failed just after a re-negotiation, and only failed for the
new ISAKMP SA, then the router or switch did not send delete messages for any
IPsec SAs that were also removed. This could mean that encrypted traffic sent
from the peer was lost.
This issue has been resolved. If heartbeats fail, the router or switch now correctly
sends the peer device a delete message for any removed IPsec SAs.
CR00013220
ISAKMP
3
Previously, if an ISAKMP policy was configured with set isakmp policy=name
prenegotiate=true and the peer was unresponsive, then at start-up the router
or switch sent fewer ISAKMP message retransmissions than the configured
msgretrylimit value.
This issue has been resolved.

Values for some DVMRP settings (including ttlthreshold and metric) were not
saved in the configuration file or output resulting from the commands create
config and show config dynamic. If the router or switch rebooted, the values
were not applied.
This issue has been resolved.
CR00013525
Stack
3
Different versions of the management stacking feature are not compatible with
each other, which means that AT-9924Ts or x900-24XT series switches can only
be stacked with other AT-9924Ts or x900-24XT switches.
This software version includes checks to prevent incompatible software from
being stacked.
CR00013547
VLAN
3
When DHCP snooping was enabled on the router or switch, performing a walk
of the MIB variables in that router or switch could result in incorrect termination
of the walk. This was because certain SNMP packets were incorrectly interpreted
as DHCP packets.
This issue has been resolved.
CR00013588

At low SHDSL bitrates, the EOC channel exhibited many spurious CRC errors.
This issue has been resolved.

NAT-T, IPsec
-
This software version supports more versions of IPsec NAT-T. As well as the
existing support for versions 2 and 8 of the NAT-T draft, the router now:
■ supports NAT-T draft version 3, as defined by draft-ietf-ipsec-nat-t-ike-03.txt.
This version has also been implemented by SonicWALL in its EnhancedOS.
■ supports RFC 3947. This RFC has also been implemented in Linux’s Openswan,
for example (www.openswan.org).
■ accepts and sends the IPsec draft version 2 Vendor ID string when the hash
does not include a carrage return. Therefore it accepts and sends a hash of
“draft-ietf-ipsec-nat-t-ike-02” as well as a hash of “draft-ietf-ipsec-nat-tike-02\n”
■ displays some other Vendor IDs in debugging information even though the
router does not support these versions. Such Vendor IDs are followed by the
phrase “info only”.
CR00013444
IP Gateway
-
RIPv2 can now use authentication passwords that contain almost any printable
character, including characters such as $, % and &. The ? character is interpreted
as asking for parameter help, so this is not usable anywhere inside a password.
Also, a password cannot contain double quotes (") as the first character of the
string.
The RIP password length is now strictly enforced at 16 characters. The command
handler no longer accepts a password with more characters than this.

DHCP
1
In some configurations in which the DHCP server was enabled, the router or
switch compacted its flash memory frequently. This occurred because the DHCP
server unnecessarily updated record files in flash memory even if the record had
not changed.
This issue has been resolved, so that DHCP records are only updated when
necessary. Note that if the router or switch has NVS memory, it stores DHCP
records in NVS by preference, instead of in flash memory.

CR00009213
MSTP
2
Because of an MSTP issue, the switch did not always send a BPDU with an
agreement flag to its designated bridge, even if the switch was synchronised with
the latest spanning tree information from the designated bridge. This prevented
the designated port on the designated bridge from making a fast transition to
the forwarding state. The result was that the network could take up to two times
the “forward delay” time to fully converge.
This issue has been resolved.
CR00009826
IP Gateway
2
When a static ARP is deleted, the router or switch sends out an ARP request to
attempt to create a dynamic ARP for that IP address. Previously, the router or
switch did not process the ARP response correctly and therefore did not add the
ARP to its ARP table.
This issue has been resolved. When a static ARP is deleted, the router or switch
attempts to create a dynamic ARP for that IP address, and will successfully add it
to the ARP table if a device responds.

IPv6
2
For IPv6, if there were multiple equal cost multipath (ECMP) static routes to a
destination, and one or more links for the routes became inactive, the inactive
route was sometimes still chosen for forwarding. This caused brief data delivery
failure to the destination.
This issue has been resolved.
CR00012534
IP Gateway
2
If the router or switch received an IP packet that had been sent as an Ethernet
broadcast, the router or switch responded as if the packet had been sent to its IP
address, even when the packet was destined for a different IP address. In
particular, the router or switch processed and responded to ICMP and TCP
packets that were sent as Ethernet broadcasts to different IP addresses. These
caused the router or switch to send ICMP echo responses or TCP reset packets.
This issue has been resolved. Such Ethernet broadcast packets are generally not
valid packets, so the router or switch now discards them.

When the WAN load balancer was used with IP NAT (instead of firewall NAT), and

This issue has been resolved.
Note that the WAN load balancer is not designed for use with IP NAT, because IP
NATs are not associated with interfaces. Configurations that use an IP NAT cannot
vary the global IP address (the gblip parameter) based on the outgoing interface,
so the WAN load balancer sends all traffic out with the same source address.
Therefore, the return traffic probably comes back via the WAN load balancer
resource that is associated with the global IP. The impact is that the WAN load
balancer balances the outgoing traffic but not the return traffic.
We recommend using firewall NAT instead of IP NAT with the WAN load balancer.
CR00012624
VRRP,
IP Gateway
2
Under certain network conditions in which VRRP entities become temporarily
unsynchronised, the router or switch could receive a gratuitous ARP from a selfelected VRRP master when the router or switch was still the master. This caused
the existing master to create an ARP entry that incorrectly redirected packets
towards the other VRRP entity even after the other entity had become a slave
again.
This issue has been resolved. The router or switch no longer accepts gratuitous
ARPs from other VRRP entities while it is still the Master.

After the AR770S rebooted, the Port Link/Activity and Duplex/Collision LEDs

This issue has been resolved. The router detects the problem and recovers from
it, if possible. If it cannot recover from the problem, it generates a log message
of severity 6, module SWK, type REST, and subtype FAIL. The log message says
“An LED error has been detected, please power-cycle the device. If this message
appears again, contact your technical support representative for help.”

However, the command create config did not create a valid configuration file

■ The log messages output on an asynchronous port were corrupt.
■ When log messages were output to an asynchronous port, that port was
(correctly) locked. However, the port remained locked after the asynchronous
log output definition was destroyed, and after the log output's destination
was changed from asynchronous to something else.
■ It was possible for a user to change the log output destination to an
asynchronous port while the user was logged into the asynchronous port. This
resulted in the user losing access to the command line interface.
■ It was possible to create a log output definition with an asynchronous port as
the destination even when another user was logged into that asynchronous
port. This resulted in the other user losing access to the command line
interface.
■ If a user changed the log output destination to an asynchronous port and
specified invalid parameters in the command, an error message was displayed
but the new output destination was saved anyway.
■ The set command allowed a user to specify an asynchronous port as the
destination without specifying the asynchronous port number. The number
defaulted to asyn0, which may not have been the desired port.

LSAs. However, networks advertised into a transit area should not be aggregated
into summary LSAs. Previously, the router or switch advertised aggregated
summary LSAs into transit areas when a range had been configured.
This issue has been resolved. When the router or switch is advertising into a
transit area, it ignores any configured range.

If a AT-8624PoE switch had a sticky fan, the fan constantly toggled between
running at full speed and slowing down. This meant that the fan continuously
generated alarms.
This issue has been resolved. If the fan reports an error more than 3 times in an
hour, it now remains at its maximum speed setting.

On the AT-8624PoE switch, a fan fault alarm was not generated when the fan
speed dropped to 70% of the expected speed.
This issue has been resolved. When the speed drops to 70% or less, a alarm is
now generated.

Software Version 2.8.1 introduced a new msgtype parameter for the command
add igmp filter, which enables users to filter on IGMP query, report or leave
messages. This parameter was mistakenly made compulsory. Therefore, if an
existing configuration script contained IGMP filters, and the router or switch
restarted with that configuration, the filters did not work.
This issue has been resolved. The msgtype parameter is now optional, with a
default of report.

IPsec
4
In output of the commands show ipsec policy and show ipsec policy
sabundle, the value for the number of bytes currently used by each SA bundle
was sometimes truncated.
This issue has been resolved, and both commands now display the correct
number. As part of this, output of the command show ipsec policy has been
modified so that the expiry limits in bytes and in seconds display on separate
lines.
Also, if the expirykbytes parameter of the command create or set ipsec
bundlespecification was given a value higher than 4193280, the router or
switch instead used a lower value.
This issue has been resolved. If you specify a value above 4193280, the router or
switch now displays a warning message and sets the expiry limit to 4193280
kbytes.

Previously the switch allowed users to specify the tag parameter when creating
or modifying a blackhole route with the commands add or set ip route.
However, blackhole routes cannot be tagged, so the switch did not apply the tag
setting in its saved configuration.
This issue has been resolved. If a command contains both the blackhole and tag
parameters, the switch now returns an error message.

L2TP
-
The connection between the router or switch, acting as an LNS, and a third party
peer, acting as an LAC, can sometimes fail during PPP link negotiation. Frequent
negotiation failures can indicate a compatibility problem between the third party
peer and Proxy Authentication responses from the router or switch. With this
enhancement, you can now disable Proxy Authentication on the router or switch
for situations where the third party equipment is not compatible. Use
proxyauth=off in the command:
add l2tp ip=ipadd[-ipadd] ppptemplate=0..31
[number={off|on|startup}] [pre13={off|on}]
[proxyauth={off|on}]
[tosreflect={off|on|false|true|no|yes}]
The default for proxyauth is on. Proxy Authentication should not be disabled
unless necessary.
To see whether Proxy Authentication is turned on or off, use the command:
show l2tp ip
and check the new Proxy Authentication entry.

Previously, a user could delete the preferred software release and the current
boot configuration file (by using the command delete file), without first setting
a new preferred release or boot configuration file. Therefore, it was possible to
accidentally delete these files, which caused network disruptions if the router or
switch restarted. If the router or switch restarted after the user had deleted the
preferred release, it booted from the fallback software. Similarly, if the router or
switch restarted after the user had deleted the current boot configuration file, it
started up with no configuration.

CR00011277
Stacked devices are now SNMP accessible through a single IP address. The MIB
Object stackSnmpHost (at-stack.mib) is used to determine which stacked device
is currently responding to SNMP Requests. By setting the value of
stackSnmpHost, an SNMP manager can chose any one of the stacked switches
to poll. After a new value is set successfully, a new SNMP agent is chosen. On
SNMP V1 and V2c operations, the new agent is immediately ready to talk to the
manager. On SNMP v3 operations, the manager needs to re-run engine discovery
to re-synchronize the agent and manager.
Traps and notifications from stacked devices now include an extra object called
hostID, which gives the value of the switch’s host ID. This identifies which stacked
switch produced the trap or notification.
